For more complex machines, we will send engineers to your country to assist with installation and training. However, there will be additional costs for engineers, including wages, visa fees, round-trip airfare, and accommodation, which will be borne by the buyer.
3,How is quality inspection carried out after welding on the spot welding machine?
Answer: Quality inspection after welding on the spot welding machine mainly includes visual inspection, destructive testing, and non-destructive testing. Visual inspection mainly observes the appearance quality of the weld, such as whether the weld is smooth and free of cracks, etc. Destructive testing involves mechanical property tests such as tensile and bending tests conducted on samples to evaluate the strength of the weld. Non-destructive testing includes methods such as X-ray inspection and ultrasonic testing to detect defects inside the weld. Select appropriate testing methods for quality inspection based on specific requirements and industry standards.
4,How is the cooling system of the spot welding machine maintained?
Answer: The cooling system of the spot welding machine is crucial for ensuring stable.
